Description

Technical Field

[0001] This utility model relates to the field of water pipe laying technology, and in particular to a docking device for water pipe laying. Background Technology

[0002] Water pipe laying is an important part of the urban water supply system. It is usually installed underground. During the water pipe laying process, a docking device is needed to connect two adjacent water pipes.

[0003] For example, in the prior art, the patent with authorization announcement number CN221075485U discloses a docking device for laying water pipes. This device pushes the docking connector into the second clamping ring of the clamping mechanism. The clamping block enters the clamping mechanism under the pressure of the second clamping ring until the clamping part reaches the second clamping groove. Then, the docking connector is rotated until the first clamping ring is clamped in the limiting cover plate to complete the installation. When disassembly and repair are required, the docking connector is twisted to move the clamping block and the first clamping ring into the gap between the two sets of second clamping rings and then pulled out directly to complete the disassembly. This realizes the function of convenient disassembly, facilitates maintenance and replacement, and reduces the workload of water pipe maintenance.

[0004] However, the two connectors of this device are inserted into the two pipes that need to be connected, but the pipes that need to be connected cannot be moved, which makes it impossible to pull the connectors at both ends of the connector out of the pipes that need to be connected, affecting the normal disassembly of the connectors. Disassembly can only be achieved by cutting off the connectors or forcibly destroying the connectors, which increases the cost of use. Therefore, a connector for laying water pipes is designed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology and to propose a docking device for laying water pipes.

[0006] The technical problem to be solved by this utility model is to provide a docking device for laying water pipes, which solves the problem in the prior art that the device cannot fix the end of the motor connection wire when winding it up, thus affecting the winding efficiency.

[0007] This utility model provides a docking device for laying water pipes, including a connecting pipe, an anti-detachment ring, a slip ring, and an internal threaded connector. Anti-detachment rings are fixedly provided at both ends of the outer surface of the connecting pipe, and slip rings are sleeved at both ends of the outer surface of the connecting pipe. An internal threaded connector is fixedly provided on the outer surface of the slip ring.

[0008] The anti-detachment ring includes an annular groove, a first spring, and a sealing rubber ring. The anti-detachment ring has an annular groove on one side of its surface facing the center of the connecting pipe. Multiple first springs are fixedly installed in the annular groove, and a sealing rubber ring is fixedly installed at the other end of each first spring.

[0009] Preferably, the outer diameter of the anti-detachment ring is not greater than the outer diameter of the slip ring, and the sum of the lengths of the two internal threaded connectors is less than the length of the connector tube.

[0010] Preferably, the annular groove matches the sealing rubber ring, and the sealing rubber ring and the annular groove are airtightly connected.

[0011] Preferably, when the first spring is in its naturally extended state, one end of the sealing rubber ring is inside the annular groove and the other end extends out of the annular groove; when the first spring is in its maximum compressed state, the sealing rubber ring is completely embedded in the annular groove.

[0012] Preferably, a vertical plate is fixedly installed on the outer surface of the internal threaded connector facing the center of the connector. A through hole is opened on the upper part of the vertical plate, and a limit rod is installed through the two through holes. Positioning holes are opened on the left and right sides of the upper surface of the limit rod. A second spring is fixedly installed on the bottom inner side of the positioning hole, and a positioning post is fixedly installed on the other end of the second spring.

[0013] Preferably, when the second spring is in its naturally extended state, half of the positioning post extends out of the positioning hole, and when the second spring is in its maximum compressed state, the positioning post is completely embedded in the positioning hole.

[0014] Preferably, the distance between the two positioning posts is equal to the distance between the two vertical plates when the slip ring is tightly attached to the anti-detachment ring.

[0015] Compared with the prior art, this utility model has at least the following beneficial effects:

[0016] 1. This utility model, by setting up a connecting pipe, an anti-detachment ring, a slip ring, and an internally threaded connector, ensures that the distance between two water pipes to be connected is equal to the length of the connecting pipe during water pipe laying. The connecting ends of the water pipes are made with external threads that match the internally threaded connector. When connecting two water pipes, the connecting pipe is placed between the two pipes, and then two slip rings are slid to both sides, causing the two internally threaded connectors to move in opposite directions. The internally threaded connectors are threaded onto the external threads of the two water pipes to be connected until the slip ring contacts the surface of the anti-detachment ring. The slip ring compresses the sealing rubber ring, pressing it into the annular groove. The first spring is compressed, and its rebound force causes the sealing rubber ring to adhere tightly to the side of the slip ring, achieving a sealing effect between the anti-detachment ring and the slip ring, preventing leakage.

[0017] 2. When a leak occurs at the joint pipe and the joint pipe needs to be repaired and disassembled, this utility model only requires rotating the two internal threaded joints to remove them from the two connected pipes. By sliding the two slip rings in opposite directions, the two internal threaded joints are no longer fitted onto the water pipes that need to be connected, and the joint pipe can be removed for repair or replacement, increasing work efficiency and reducing the workload of water pipe maintenance.

[0018] 3. This utility model, by setting up vertical plates and limiting rods, ensures that when the two internal threaded connectors on the connecting pipe are connected to two water pipes that need to be connected, both vertical plates face the same direction. Then, the positioning pin on the limiting rod is pressed into the positioning hole, and the second spring is in a compressed state. Then, the limiting rod is inserted into the through hole on the two vertical plates, so that the two positioning pins are between the two vertical plates, achieving the effect of locking the two internal threaded connectors together. This prevents the internal threaded connectors from rotating, which could cause the threaded connection between the internal threaded connectors and the water pipes to loosen, thus ensuring the stability of the connecting pipe when connected to the water pipes.

[0026] Example:

[0027] like Figures 1-4 As shown, an embodiment of this utility model provides a docking device for laying water pipes, including a connecting pipe 1, an anti-detachment ring 2, a slip ring 3 and an internal threaded connector 4. Anti-detachment rings 2 are fixedly provided at both ends of the outer surface of the connecting pipe 1. Slip rings 3 are sleeved at both ends of the outer surface of the connecting pipe 1. An internal threaded connector 4 is fixedly provided on the outer surface of the slip ring 3.

[0028] The anti-detachment ring 2 includes an annular groove 201, a first spring 202 and a sealing rubber ring 203. The anti-detachment ring 2 has an annular groove 201 on one side surface facing the center of the connecting pipe 1. Multiple first springs 202 are fixedly installed in the annular groove 201, and a sealing rubber ring 203 is fixedly installed at the other end of the first spring 202.

[0029] In this embodiment, the outer diameter of the anti-detachment ring 2 is not greater than the outer diameter of the slip ring 3, and the sum of the lengths of the two internal threaded connectors 4 is less than the length of the connector 1, so that the two internal threaded connectors 4 can slide completely onto the connector 1 without protruding from both ends of the connector 1.

[0030] In this embodiment, the annular groove 201 is matched with the sealing rubber ring 203, and the sealing rubber ring 203 and the annular groove 201 are connected in an airtight manner to ensure sealing.

[0031] In this embodiment, when the first spring 202 is in its naturally extended state, one end of the sealing rubber ring 203 is inside the annular groove 201, and the other end extends out of the annular groove 201. When the first spring 202 is in its maximum compressed state, the sealing rubber ring 203 is completely embedded in the annular groove 201.

[0032] By setting up a connecting pipe 1, an anti-detachment ring 2, a slip ring 3, and an internal threaded connector 4, during the laying of water pipes, the distance between the two water pipes to be connected is equal to the length of the connecting pipe 1, and the connecting ends of the water pipes are made with external threads that match the internal threaded connector 4. When connecting two water pipes, the connecting pipe 1 is placed between the two water pipes to be connected, and then the two slip rings 3 are slid to both sides, so that the two internal threaded connectors 4 move in opposite directions. The internal threaded connectors are threaded onto the external threads of the two water pipes to be connected, until the slip ring 3 contacts the surface of the anti-detachment ring 2. The slip ring 3 squeezes the sealing rubber ring 203 and presses the sealing rubber ring 203 into the annular groove 201. The first spring 202 is in a compressed state, and the rebound force of the first spring 202 makes the sealing rubber ring 203 fit tightly against the side of the slip ring 3, thereby achieving the effect of sealing between the anti-detachment ring 2 and the slip ring 3 and preventing water leakage.

[0033] When a leak occurs at the connector 1 and it needs to be repaired and disassembled, simply rotate the two internal threaded connectors 4 to remove them from the two connected pipes. Then, slide the two slip rings 3 in opposite directions so that the two internal threaded connectors 4 are not fitted onto the water pipes that need to be connected. This allows the connector 1 to be removed for repair or replacement, increasing work efficiency and reducing the workload of water pipe maintenance.

[0034] In this embodiment, a vertical plate 5 is fixedly installed on one end of the outer surface of the internal threaded connector 4 facing the center of the connector 1. A through hole 501 is opened above the vertical plate 5. A limit rod 6 is installed through the two through holes 501. A positioning hole 601 is opened on both the left and right sides of the upper surface of the limit rod 6. A second spring 602 is fixedly installed at the bottom of the inner side of the positioning hole 601. A positioning post 603 is fixedly installed at the other end of the second spring 602.

[0035] In this embodiment, when the second spring 602 is in a naturally extended state, half of the positioning post 603 extends out of the positioning hole 601, and when the second spring 602 is in a maximum compressed state, the positioning post 603 is completely embedded in the positioning hole 601, and the positioning post 603 will not affect the insertion of the limiting rod 6 into the through hole 501.

[0036] In this embodiment, the distance between the two positioning pins 603 is equal to the distance between the two vertical plates 5 when the slip ring 3 is tightly attached to the anti-loosening ring 2. This facilitates the use of positioning pins 603 to prevent the relative displacement of the two internal threaded connectors 4, thereby preventing the internal threaded connectors 4 from loosening.

[0037] With the vertical plate 5 and the limiting rod 6 installed, when the two internal threaded connectors 4 on the connecting pipe 1 are connected to the two water pipes that need to be connected, the two vertical plates 5 are oriented in the same direction. Then, the positioning pin 603 on the limiting rod 6 is pressed into the positioning hole 601, and the second spring 602 is in a compressed state. Then, the limiting rod 6 is inserted into the through hole 501 on the two vertical plates 5, so that the two positioning pins 603 are between the two vertical plates 5, thereby achieving the locking effect between the two internal threaded connectors 4, preventing the internal threaded connectors 4 from rotating and causing the threaded connection between the internal threaded connectors 4 and the water pipes to loosen, thus ensuring the stability of the connecting pipe when connecting to the water pipes.

[0038] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
